The CY7C024/024A/0241 and CY7C025/0251 are low power CMOS 4K x 16/18 and 8K x 16/18 dual-port static RAMs. Various arbitration schemes are included on the CY7C024/ 0241 and CY7C025/0251 to handle situations when multiple processors access the same piece of data. Two ports are provided, permitting independent, asynchronous access for reads and writes to any location in memory. The CY7C024/ 0241 and CY7C025/0251 can be used as standalone 16 or 18-bit dual-port static RAMs or multiple devices can be combined to function as a 32-/36-bit or wider master/ slave dual-port static RAM. An M/S pin is provided for implementing 32-/36-bit or wider memory applications without the need for separate master and slave devices or additional discrete logic. Application areas include interprocessor/multiprocessor designs, communications status buffering, and dual-port video/graphics memory.
